PRINCETON, N.J. — PRINCETON, N.J. (AP) — School officials say reports of gunshots at a historic building on Princeton University's campus have been determined to be unfounded and the "all clear" has been given.

The New Jersey Ivy League university says that the school's safety office received a report of shots fired in Nassau Hall at 7:55 p.m. Tuesday. Police cordoned off the area and checked the building before giving the "all clear" at about 10:25 p.m. No injuries were reported.

Nassau Hall is Princeton's administrative center. Princeton's website calls Nassau Hall the centerpiece of its campus and a university and national landmark. It says it moved classes from Newark to Nassau Hall in Princeton when the building was completed in 1756.
